  • The Food and Drug Administration has already approved his technique for human trials, and he has secured funding from the Army to conduct the feasibility phase. Dr. Rhee is currently lobbying for funds to conduct a full trial. If he’s successful human trials could begin as early as next year.
  • What Dr. Rhee hopes to test on humans is a method he worked out for the past couple decades on pigs. Patients would be injected with a cold fluid to induce severe hypothermia. Clinically hypothermia is characterized by the drop of a person’s body temperature from its normal 98.6 degrees Fahrenheit (37 degrees Celcius) to lower than 95 degrees (35 C). Below 95, the heart, nervous system and other organs begin to fail. The strict range is indicative of a metabolic system with strict temperature requirements for proper function (death waits only a few degrees the other way as well). Dr. Rhee’s method involves injecting patients with a cold fluid that would bring the body’s temperature down to 50 degrees Fahrenheit (10 C). Sounds chilling, but when he induced the extreme hypothermia in pigs they came out just fine. Heart function, breathing, and brain function was completely normal.
  • Dr. Rhee is no stranger to high-stakes medicine. The native South Korean was trained at the Uniformed Services University Medical School in Bethesda, Maryland. Following a fellowship in trauma and critical care at the University of Washington’s Harborview Medical Center he served in the US Navy as director of the University of South California’s Navy Trauma Training Center at Los Angeles County. He was then sent to Afghanistan where he was one of the first surgeons at Camp Rhino. Later he started the first surgical unit at Ramadi, Iraq. His cool under fire was on display nationally as he performed surgery on US Representative Gabrielle Giffords after she was shot through the skull in the Tucson shootings this past January. His experience with induced hypothermia came into play the night of the shootings when Dr. Rhee removed part of the congresswoman’s skull. The wound had raised her body temperature and began “cooking the brain.” He used a device to cool Rep. Giffords’ skin.

    The new EPI Life mobile phone comes complete with mini electrocardiogram. "We think it's a revolution. It has clinical significance," EPI medical chief Dr. Chow U-Jin said at the mobile industry's annual conference in Barcelona. "Anywhere in the world you can use it as a phone but you are also able to transfer an ECG and get a reply," Chow said. "If you get a normal reply it will just be an SMS," he added. "If it's severe, you get a call: 'Sir, an ambulance is on the way'." EPI Life has three hospitals in Singapore, all of which carry the phone users' history. EPI Life costs $700 (516 euros), the price of a top range smartphone, and 2,000 of them have been on the market since 2010.

  • Scientists have successfully modified the white blood cells of 12 patients living with HIV, making their cells resistant to the retrovirus and improving the study participants' overall ability to fight off infection. The researchers achieved this result through a gene editing technique, described today in
  • Unlike the child who went into HIV remission a year ago, the patients in this study continue to test positive for HIV. But the results of this Phase I clinical trial still represent a promising debut for HIV treatments involving tailored gene therapy, as the white blood cells persisted for nearly a year after transfusion.
